hello.
ca sa incep cu inceputul: am phpBB 2 0 11 cu modurle:

• album 202
  archive_sei_mod 106
  attach_mod 2311
  Complete Database Backup v1.0.1
  Forum Permissions_list 101
  Latest Topics
  moderator modcp 105
  overall forum permissions 102
  pageloading 114
  quickreplayquote 115
  smart login redirect
  wellcome index
  admin phpInfo

ce se intampla: cand am instalat Complete Database Backup v1.0.1 facea bine-merci dump la toate tabelele - inclusiv alea suplimentare.
Dar la un moment dat , dupa ce am mai instalat cateva moduri, nu mai merge.Adica da err :
Failed in get_table_def (show fields)

DEBUG MODE

SQL Error : 1064 You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

SHOW FIELDS FROM

Line : 375
File : c:\appserv\www\fish\bb\admin\admin_db_utilities.php

de ce ? si cum scap de ea?
din ce am inteles eu are probleme la obtinerea listei cu tabele din baza.

merci
